The Cysic cross-chain bridge has been restored, and approximately 7.2 million CYS tokens have been permanently burned on BNB Chain.

Cysic has announced that its cross-chain bridge has fully recovered following the security incident, allowing users to resume bridging CYS between the Cysic mainnet and other supported chains. A total of 7,200,002 CYS tokens have been permanently burned on BNB Smart Chain. On October 17, an attacker exploited a vulnerability in the cross-chain bridge’s message processing to mint 10 million CYS tokens without authorization. The attacker then sold approximately 7.2 million tokens and transferred around $727,000 in proceeds to Ethereum. Cysic subsequently suspended bridging services and blacklisted the attacker’s address to freeze the remaining ~2.8 million CYS. The project confirmed that assets in the mainnet and user wallets were unharmed. The foundation previously announced plans to burn ~7.2 million CYS from reserves to offset the unauthorized minting and recalibrate token economics, and two burn transactions have now been completed.
